With the benefits of cloud computing, cloud services like Infrastructure as a Service (IaaS) and Hardware as a Service (HaaS) enable scientists and researchers to run their HPC applications in the cloud without the upfront investment associated with the traditional HPC infrastructure. Traditionally, in the scientific research domain, HPC refers to the use of supercomputers, grid environments, and/or clusters of computers to solve computation-intensive and/or data-intensive problems. The traditional HPC systems are expensive and sometimes require huge start-up investment, technical and administrative support, and job queuing. The computational performance and financial costs of operating HPC applications in the cloud when IaaS or HaaS is leased are examined in this research. We discover that, in comparison to IaaS, HaaS dramatically lowers the cost of running HPC applications in the cloud by 20% without appreciably affecting the application's performance. Additionally, we discovered that HaaS offers significantly better computational performance than IaaS.and HPC-An overview of several cloud computing models, including several kinds of cloud environments like Public Cloud, Private Cloud, is given in this study article. Community, Hybrid, and Cloud clouds. The models of Platform as a Service (PaaS), Infrastructure as a Service (IaaS), and Software as a Service (SaaS) are also covered in detail. There is a thorough discussion of the security risks related to cloud computing, including compromised passwords, data breaches, compromised interfaces and APIs, exploited system vulnerabilities, and account hijacking.
